I have two PCs:
- PC1 with Ubuntu 10.4
- PC2 with DOS & Windows 3.11
They are connected by a serial null-modem cable. I used the PC2 as serial terminal, but now i wanna connect it to my LAN. How can I make my PC1 a SLIP server?

Im trying to make an ubuntu server box my entrypoint to my networking. Meaning itll function as a server, a firewall, and a gateway. so i already installed dhcp3 and a dns server.
I have 2 ethernet cards in it. So now i wonder, should i the second card into a router's modem/wan port and make the router a switch? or should i plug it into one of the routers lan ports?
I am trying to make my pc as a small web server. so i followed the steps below
1) Configure the router - Active Port Forwarding
Private IP Protocol Type Public Start Port Public End Port Connection 192.168.1.3 ALL 78 78
[Code]....
However, when i am trying to use public ip. it goes to the router's configuration page.
I have the following setup:
Location A:
Internet -> ISP 1 -> Firewall 1 (external IP address) -> Web Server 1 (internal IP address)
Location B:
Internet -> ISP 1 -> ISP 2 -> Firewall 2 (external IP address) -> Web Server 2 (internal IP address)
I want to find out if I can failover to another location without having to make changes on the DNS server. Just by redirecting traffic from ISP 1 router to ISP 2 router.
I have a Synology home server at home. I have a laptop with Linux Mint 8 (Helena) installed. I can access my server's shared files using LAN through Places>Network>Windows Network>Workgroup>Server>Shared files. I can also access the files through a web browser. Samba is installed. The problem is when I use the wireless lan of my laptop, I cannot access the server and the files anymore locally even through a web browser.
I tried Connect to Server through Windows Share but what I get is "Could not display "smb://server/".".
I have been working in Linux for the past two years.And working in squid for the past 6 months.The following is my Setup
ETH1 - ISP1 (Active)
ETH2 - LAN (Active)
ETH3 - ISP2 (Inactive)
Using Iptables I forward 80 port through squid (3128).Other ports just get connected in the proxy machine itself since it has IP_FORWARD enabled. All my client machines browsers enabled with "Use proxy 3128". I just want to make all the port to pass through squid server.
I have a client's linux server where someone added a script which sends spam mails from the server's local loopback address (127.0.0.1) all my seniors worked on it and couldn't trace the script on the server this issue was going for a week, now I have an idea to bring down the loopback interface of that particular server(ya, that was not a permanent solution but just had an idea), but my support manager told that it will bring the whole server down(so far as i have learn't loopback address is used only for testing the NIC card's functionality), is that really bring the server down.?. How ever i tried this using a test machine all the connections works fine even after i bring down the loopback interface. As my client's server is a production server i can't test it there without clear knowledge, can any one help me out whether will it bring down the server or will it cause any side effects on it(i know that you guys are experts so i am asking it here)?
View 5 Replies View RelatedI'm trying to make a DHCP server work on my CentOS 5.4 box, but I have placed it on another subnet than the one that it is going to serve. I use a helper address on my router to make the the DHCP requests being routed to the DHCP server on the other subnet.

I'm trying to find a command to tell nslookup, "I want you to try to resolve hostname X using DNS server Y, and if the lookup fails, just output failure do NOT fail over to some other DNS server as a backup and use it to try to resolve the same hostname."I'm trying to follow the man page instructions for doing this, but it doesn't seem to work. The man page for nslookup on my system (CentOS 5.5) includes the line:
"[no]fail Try the next nameserver if a nameserver responds with SERVFAIL or a referral (nofail) or terminate query (fail) on such a response."But if I try using that option, the output seems to indicate that after the lookup failed on ns1.afraid.org, nslookup failed over to 208.67.220.220 (the first nameserver listed in my resolv.conf -- an OpenDNS nameserver) and used it to resolve the hostname instead.
I'd love a hint or two on the following problem. I've set up iptables rules to forward all connections to port 3306 to a non-standard mysql port on a remote server. This works, except that I need to deal with the loopback interface in a special way and I'm stuck.
Code:
iptables -t nat -A PREROUTING -p tcp --dport 3306 -j DNAT --to 128.XXX.XXX.XXX:3197
iptables -A FORWARD -p tcp -d 128.XXX.XXX.XXX --dport 3197 -j ACCEPT
iptables -t nat -A POSTROUTING -j MASQUERADE
Since locally-generated packets will never hit the PREROUTING rule, you'll need to setup a near identical rule using OUTPUT to make it work. Here is what I've tried:

When my pc is connected directly to the LAN modem, my server can go online, ip connects to the domain and everything is cool.
When my pc connected to the router which is connected to the modem, I can't make my server go online. It asks for some linksys authorisation.
How can I teach my server to ignore my router and go directly to the modem. Unfortunately I can't just connect my server to the modem couse 3 more PCs are connected with the hub.

View 3 Replies View RelatedI've been tried to be system admin, programmer, network admin, or network engineer. So, I've been studying this and that... what so ever struggling to find my talent. Back in 2007-2008, I was MS server admin/comm tech. I saw a building running MS server for user computers and Red Hat 9 as a main system server. MS sever was a just one of the user accounts of Linux server. When I log in to Linux, I could see log menu to access MS server. How could somebody make this creative thing?I'm now a Network engineer because working with CISCO router and switch is easier than working as programmer or server admin. I've studied Oracle 10 and VMWARE also but there are ceasless stuffs that I need to study... For now, in regards of my limited brain power, network engineer is proper for me.

The system was fine for like 3 weeks until recently when it started slowing down. Apparently, eveything is normal when you are accessing the server, for example when you are browsing on the database web interface; but problem is when you start working in the database, when you try submitting into the database, its really slow on processing, i have to first restart the mysql;
Could it be RAM? or the SQL itself?
